For a cohesive champagne cocktail, consider removing the stick from the popsicle or leaving it intact for a gradual flavor infusion.
French brut Champagne complements the popsicle's intense berry flavor, while sweeter prosecco should be more fruity than floral for a balanced taste.
Sparkling rosé may not pair as well due to its floral notes, consider alternative sparkling beverages for a non-alcoholic variant, and casual plastic cups are suitable for serving.
